Well, I did try them all, by buying every switch type. I still love buckling springs, obviously, and fake green Alps weren't bad. I started my MX journey with Blacks, but I'm not fond of them anymore. I hated Blues and Ghetto Greens. Not a big fan of standard Clears, but I didn't give them much of a test. I really like Reds, Browns, and Ergo Clears. I can use any of those 3 interchangeably.
I recommend MX Browns to new users of mechanical keyboards, because they are light and tactile, and also they are readily available. Ergo Clears are not a standard switch type. And Reds can be annoying, depending upon your typing habits, due to extraneous keypresses. All that said, I prefer any switch type on a plate mounted keyboard to a PCB mounted version.
